PUMP.

SPECIFICATION forming part of Letters Patent No. 576,521, dated February2, 1897. Application filed July 25, 1896. Serial No. 600,542. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, EDWARD G. STAPLE, a citizen of the United States,residing at Oshkosh, in the county of Winnebago and State of Wisconsin,have invented certain new and useful Improvements in Pumps; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it ap-IO pertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in pumps, and has more particularrelation to improvements in the ordinary cistern-pump known as andcalled the pitcher-pump.

My invention consists, essentially, in a supportin g-base having acircular depression sur 2o rounding the suction-pipe opening and acorresponding circular flange integral with the suction-pipe and capableof fitting closely into said depression, packing covering the jointbetween the flange and the depression, and

means for clamping the cylinder portion of the pump to the base.

My invention also consists of certain other novel features andconstructions, which will be hereinafter more specifically shown andconsidered.

Heretofore in this class of cistern-pumps the suction-pipe has beenconstructed integral with the base of the pump, and as this class ofpumps are cast-iron pumps it has 3 5 been impossible to make furtherconnection or extension of the suction-pipe except by soldering theextension, and therefore the use of lead pipes Was necessary. In otherwords, ordinary iron pipe-couplin g could not be made to extend thesuction-pipe.

In my invention the suction-pipe of the pump is supported from the baseand may be constructed of wrought or malleable iron, so that ordinarypipe-couplings may be attached and an iron pipe used to extend it intothe cistern.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical central section of the pump embodying my invention. Fig.2 is a top view of the base and lower valve, the cylinder or top portionof the pump being removed.

Similar letters refer to similar parts in each view.

A in the drawings represents the base of the pump, which is attached tothe top of the sink or other support by means of screws a a. The base Ahas a circular flat top A, through which extends a central suction-pipeopening B. Surrounding this opening is a circular depression O.Acorresponding circular flange E, integral with the suction-pipe D, fitsclosely into this depression 0 and with a packing F extends beyond andcovers the joint between the top A and flange E, so as to effectuallyprevent any leakage or suction of air. The cylinder or top portion G isclamped to the base by means of the screws H H, thereby compressing thepacking F and effectually preventing leakage or suction of air. Thevalve I is the same as that used in ordinary cistern-pumps, and thepacking F, connected therewith, is the same or of similar construction.7

By means of my invention the suction-pipe 7 5 D may be of wrought ormalleable iron, so that ordinary pipe-coupling D may be used to connectwith the extension of iron pipe, if it is desired, and the use of leadpipe attached by means of soldering or wiping it is not mo essary.

In the use of cistern-pumps as now constructed the cost of the lead pipenecessary is more than the cost of iron pipe, and the services of aplumber are usually necessary in connecting the pump with the extensionnecessary to reach the Water in the cistern.

Having thus described my invention,what I claim to have invented, anddesire to secure by Letters Patent, is p A cistern-pump consisting of abase or lower portion having a flat top forming a packin g-seat providedwith a central suctionpipe opening and a circular, rabbet-shapeddepression surrounding the said opening, a 95 suction-pipe having acorresponding, circular integral flange, and adapted, when fitted intosaid depression, to be flush with the fiat top of said base portionprovided at its lower end with an outwardly-extending flange having aI00 flat bottom surface, packing arranged to cover the joint formed bythe flange of the suctionpipe and the rabbeted base for preventing theleakage of air and extending beyond the same between the flat top of thebase and the flange of the upper pump portion, all around therebypacking the horizontal joint between the base and the upper pumpportion, and means for clamping the flange of the upper 1 portion to theHat top of the base and com 10 pressing the packing between the saidparts, substantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses.
